A really amazing sighting of a long, bright blue streak over McAllen, Texas, which appeared as quickly as it disappeared, has been submitted to MUFON (case 98661). Although the witness didn't take a photo of the event, they did create a digital drawing of it, which they shared along with their testimony:

It was dark, cloudy and misty around 7pm. I was at the HEB parking lot walking back to my vehicle after placing a shopping cart back into the stall and I saw a long blue streak fly across the clouds so fast, it was gone within a second. I was facing south towards HEB and the blue light streak was only visible for 1 second which spanned a quarter mile across the sky going west to east.
